Answer: a. created the Environmental Protection Agency (EPA), the Occupational Safety and Health Administration (OSHA), and the National Transportation Safety Board (NTSB).
Step-by-step explanation:
Even though former President Nixon was a proponent of reducing the powers of the Federal government, he recognized the need for certain federal government agencies at a time when economic growth had led to increased pollution and maltreatment of employees.
Agencies such as the EPA, OSHA and the NTSB were established after their respective bills went through Congress to ensure the protection of the environment and workers thereby making Nixon's administration one of the most eco-friendly ones there was.
